iff-I do hereby declare that the following isa full, clear, Iand exactdescription of the same,

UNITED STATES PATENT OFFICE certain new and useful Improvements in jAuxiliary Springs for Motor-Vehicles; Vand `reference being had to the,accompanying drawings, and to the. numerals of reference j markedthereon,` which form apart of this manufacturers to make a sin lechassis,

mounting one ystyle of body t ereony for, pleasureA and` another stylebody; for deliv-r sfery ortruck cars. While the springs acta more orless 'satisfactorily-onfthepassenger` cars and lightly. loaded deliverycars, they-I cause considerable expense, delay and ,annoyanoe, on thedelivery trucks by breakage when they are'loaded heavily.

v.It is an 'obj ect of this invention to provideauxiliary springsadapted to be easily and quickly attachedto the chassis of a Ford orother cars so arranged and disposed that they coact withthemainspringsof the car to absorb part of theshock andstress ycaused by theheavy loads.

It' isy 'a further 'and fan important obj ectf` 1 nectedwith thebrackets 6 on the brake of this invention to provide auxiliary springmechanism which largely prevents side sway or rocking of the car body onits rear springs and therebl eliminates considerable of the strain on te various parts causing longer life to the car body and suspension.

It is a further object of this invention to provide a device which notonly takes up a large part of the compression shock of the load but alsoprevents quick rebound thereby preventing snapping of a main springunder severe road conditions.

The invention (in a preferred form) consists in the matters `hereinaftermore fully pointed out and described in the drawings and ,appendedclaim.

On the drawings:

Figure 1 is a fragmentary rear elevation of a chassis provided with adevice embodying this invention.

Fig. 2 is a top plan view thereof.

This is the standard construction in Ford motor cars, and in myinvention, I take advantage of this standard construction, to effect theattachment of my auxiliary springs so that the upper bracket whichconnects with the upper end of my spring may be connected to the. frameof the car without the necessity of making bo-lt holes or any change oralteration whatever but by utiliz- 'ing standard facilities with whichthe frame of the motor car is already provided.
